besides that if you annoy them enough they just stop provide binaries 
and say "figure out how to build ffmpeg at your own jerk" the paragraph 
below is plain nonsense

and even if they provide you every single line you won't get a identical 
binary and "There is no guarantee that the releaser hasn't modified the 
sources" sounds like the next step of the OP would be like offend them 
with "you have modified the sources because my binary is not identical" 
because of his cluelessnes

a reproducable build is much more then fire up a script

I agree that I can just dump the config parameters from the binary 
itself using -buildconf. But, it doesn't mean that I can just reproduce 
the same binary with the script

you can't anyways until you use a *identical* build environment
